CONDITIONED HUNGER

Made a methodological analysis of the conditioned hunger problem. Independent measures were taken to determine if the necessary and sufficient conditions to establish a conditioned hunger response had been satisfied. In 2 experiments, using 20 male Long-Evans rats in each, the attempt to establish these conditions was not successful, and in neither case was conditioned hunger demonstrated. The methodological evaluations made in the experiments are considered necessary if strong positive or negative conclusions are to be drawn. Eating rate but not hoarding was shown to be a potentially sensitive indicator of conditioned hunger.
